ABSTRACT

The aim of this study was to examine the acute effect of aerobic exercise when performed in the morning and evening on obesity-related hormones of asprosin, spexin, lipocalin-2, and insulin in normal weight (NW) and overweight/obese (OW/OO) adults. A total of 20 adult male individuals (10 NW and 10 OW/OO) volunteered their participation. Both groups were subjected to an aerobic exercise protocol in moderate intensity (heart rate reserve of 55–59%) for 30 min at two different time periods of the day (morning: 08:00–10:00 h, evening: 20.00–22.00 h) at least 3 d apart. BeBis analysis revealed the OW/OO group consumed significantly less energy (1781.59 ± 410.71 kcal) as compared with NW group (2380.28 ± 445.50 kcal) before the evening exercise (about 3 d) (p <.05). As compared with the NW group, basal serum asprosin, insulin, and lipocalin-2 hormone levels were higher in the OW/OO group, and serum spexin level was lower in OW/OO group (p <.05). Body temperature significantly increased after morning and evening aerobic exercise in both groups. The increase in body temperature was significantly higher after the evening exercise in the OW/OO group compared to the NW group (p <.05). Significant decrease in serum asprosin lipocalin-2, and insulin levels was observed in both groups after exercise (p <.05). Evening aerobic exercise more greatly decreased serum asprosin, lipocalin-2, and insulin level in the OW/OO group as compared with the NW group (p <.05). In conclusion, it is thought that negative energy balance caused by psychological energy restriction and evening aerobic exercise, which leads to a further increase in body temperature, triggers greater decrease of orexigenic signals (suppression of appetite), and is more effective in the development of adipose tissue inflammation and insulin sensitivity, especially in OW/OO group.

摘要

这项研究的目的是研究有氧运动在早晨和晚上对正常体重（NW）和超重/肥胖（OW /肥胖者）中与肥胖相关的asprosin，spexin，lipocalin-2和胰岛素相关激素的急性影响。 OO）成人。共有20名成年男性（10名西北和10名OW / OO）自愿参加。两组均在一天的两个不同时间段（早晨：08：00–10：00 h，晚上：20.00–22.00）进行中等强度的有氧运动（心律储备为55–59％）30分钟h）至少相隔3 d。BeBis分析显示，与夜间锻炼前（约3 d）的NW组（2380.28±445.50 kcal）相比，OW / OO组消耗的能量（1781.59±410.71 kcal）显着减少（p<.05）。与NW组相比，OW / OO组的基础血清促胰蛋白酶，胰岛素和lipocalin-2激素水平较高，而OW / OO组的血清spexin水平较低（p <.05）。两组早晚进行有氧运动后体温均显着升高。与NW组相比，OW / OO组的夜间运动后体温升高明显更高（p <.05）。运动后两组均观察到血清proprosin lipocalin-2和胰岛素水平显着降低（p <.05）。与NW组相比，夜间有氧运动与OW / OO组相比，血清Asprosin，lipocalin-2和胰岛素水平的降低更大（p<.05）。总之，人们认为，由于心理能量限制和夜间有氧运动引起的负能量平衡，会导致体温进一步升高，触发食源性信号的更大降低（抑制食欲），并且在发展中更有效。脂肪组织炎症和胰岛素敏感性，尤其是OW / OO组。
